I didn't find anything wrong in a current sendmail source.  And my
desktop has had a AAAA RR for quite some time now, without a special
sub-zone to hold it.

And the last time I delved into bind, the named-xfer program that did
a zone transfer for a secondary server created a text-format file, so
it couldn't accept any new RR type it didn't know about.  Ugh.  I
hope that's been fixed.

And running into these problems is success for the 6bone, not failure.
